HAT-PIN.

Specification of Letters Patent.

Patented Nov. 23, 19115.

Application filed February 24, 1913. SeriaINo. 750,194.

To all whom it may concern Be it known that ll, CARL H. BJGRKDAHL, a subject of the King of Sweden, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in HatPins, of which the following is a specification.

My invention relates to hat-pin constructions and its object is to provide means for retaining the hat pin in place and preventing its accidental loss or displacement.

Another object is to facilitate the insertion and removal of the pin and to provide a positive lock against its longitudinal movement out of the hat.

With these objects in view my invention consists in the novel construction, combina tion and arrangement of parts, all as hereinafter described in detail, illustrated in the accompanying drawing and incorporated in the appended claim.

In the drawingFigure 1 is a plan View of a hat, partly broken away and partly in section, with my invention applied thereto. Fig. 2 is a side elevation of same partly in section. Fig. 3 is an enlarged view of the pin, section of the ha and the means for guiding and retaining the pin. Figs. 4, 5 and 6 are sections of the pin and its locking mechanism showing the operation of the latter. Fig. 7 is a perspective view of the apertured guide plate. Fig. 8 is a similar view of the binding or looking disk.

In the several views 2 represents the hat and 3 the pin as a whole consisting of a pair of prongs l and5 which diverge from the head 6. The prongs aand 5 are held in and guided by a plate 7 having a pair of apertures 8 and 9 which are engaged by the prongs. This plate is fastened to the side of the hat by means of a pair of barbs or spurs which before insertion in the hat extend at right angles from the plate as shown in dotted lines in Fig. 7 and are after insertion bent apart parallel with the plate, as indicated in the full lines, and thus secured to the hat. The prongs are made of spring metal and diverge from the head as shown in Figs. 3, 4: and 6. When the points of the prongs are in the openings 8 and 9 said prongs are held close together and substantially parallel and as the pin progresses inwardly the prongs gradually spread apart. As they cannot be withdrawn without being forced together against their spring tension the hair of the wearer, as well as the plate 7, resist accidental outward movement.

In addition to the above-described action of the prongs, additional and more positive locking means for especially valuable hatpins, are provided in a supplemental apertured plate 12 having holes 13 and 14 there through which register with the holes 8 and 9 in the plate 7. The plate 12 is free on the prongs, or unattached to the hat. Thus when the head of the pin is grasped to draw out the prongs if the wearer does not hold the plate 12 with a finger of the other hand against the plate 7 to occupy the relative positions shown in Fig. 4 the plate 12 will move with the prongs as in Fig. 5, the holes 8 and 9 will, as in Fig. 6, be brought out of line with the converging point 15 and the holes 13 and 14 producing the sudden short bends 16 and 17 shown in Fig. 5. To such bending of the prongs there will, of course, be such a decided resistance as to amount substantially to a positive stop, or a strain on the plate 7 that would tend to tear it out of the hat.

In Fig. 4 is shown a modification for the points of the prongs consisting in slight enlargements (somewhat exaggerated in Fig. 4 to more clearly show the idea) 18 and 19 which will prevent the points of the prongs from being drawn through the holes 8 and 9 or entirely releasing the hat pin from its engagement with the plate 7. Where the holes 8 and 9 are made to fit the prongs 4: and 5 almost imperceptible enlargements or upsettings at the point will accomplish this purpose. The slight projections of the points into the hair of the wearer after the pin had been withdrawn up to the enlargement stops would not interfere with the removal of the hat, which, by tilting up the entirely free side first, could be moved sidewise slightly to free the points from the hair. The modification shown in Fig. 4 obviates the necessity of guiding the points of the prongs into the holes 8 and 9. To facilitate the finding of the holes 8 and 9 the latter may be provided with outside sloping sides or conical counterbores 20 and 21 as in Fig. 4.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination with a hat, of a hat pin consisting of a head and a pair of prongs which diverge from said head, an apertured guide-plate secured to the hat and H having a bore therethrough for each of said prongs Which holds the latter spaced apart, and a locking plate With correspondingly spaced apart apertures engaged by said prongs and movable therewith to hold the prongs againstrfree movement toward each other from their point of divergence insaid head, thereby causing said prongs to bind against outward movement in said guide Copies of this patent may be obtained for five cents plate, said locking plate being rendered inoperative by manually holding same against movement With said prongs.

In testimony whereof I have hereunto set my hand in the presence of two subscribing Witnesses.
